1 Claim.

This invention relates to protectors, and its general object is toprovide an insulating device primarily designed to be attached to thebottom of dinner pails and the like of workmen 5 for use particularly intraveling on electric mine locomotives and the like, to protect the pailfrom being damaged by short circuits when accidentally placed on objectsin the locomotive circuit, as generally a hole is burned in an unprotected pail when the pail causes a short circuit.

A further object 01 the invention isto provide a protector for pails,that not only insulates the same to prevent short circuits as above setforth, but also protects the pail against wear and damage caused by hardknocks and the like.

Another object of the invention is to provide an insulating protectorfor pails, that is simple in construction, can be applied to practicallyall types of pails, is inexpensive to manufacture and extremelyefiicient in operation and service. This invention also consists incertain other 'i eatures of construction and in the combination andarrangement of the several parts, to be hereinafter iully described,illustrated in the accompanying drawing and out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which: 1

Figure 1 is a view illustratingone form of my protector applied to adinner pail.

Figure 2 is a similar view of a modified form. Figure 3 illustrates theapplication of a further modified form to a particular type of pail.

Figure 4 is a view of the form shown in Fig- 40 ure 3 applied to a pailof the usual type.

Figure 5 is a sectional view taken through the grooved form per se.

Referring to the drawing in detail and particularly to Figure 1, it willbe noted that this figure illustrates a pail indicated by the letter Aand which is of a type generally employed by workmen, and particularlyminers who generally travel on mining locomotives into and out of themines. Considerable difliculty has been experienced by the miners withtheir dinner pails, as when traveling on the mine 10- comotives thepails may he accidentally placed on objects in circuit with thelocomotive circuit, and thereby cause a short circuit which usuallyburns a hole in the bottom of the pail and ,iiange with the disk for thepurpose of accomspecifically pointed therefore makes the same uselessfor.carrying liquid, but with my protector applied to the pail, suchacasualty is impossible.

The pail A is flared outwardly adjacent its bottom and the protector forthat particular type of pail includes a base 1 that is of disk formationto cover the entire bottom of the pail and formed with the base is aninwardly flared annular flange 2. a

The protector is formed from rubber or other suitable elastic insulatingmaterial and is disposed cn the bottom of the pail as shown. When sodisposed, it will be obvious that the annular flange will grip theflared portion of the pail and thereby prevent casual, removal iii ofthe protector therefrom.. I

In Figure 2, I have illustrated another iorm of my invention that isprimarily designed for a pail of the type indicated by the letter B andwhich is provided with a bead C and the pro it tector for this type ofpail likewise includes a base disk 3 and an annular flange 4,'but itwill be noted that the flange is provided with an annular recessarranged at the juncture of the modating the bead B.

In Figures 3, 4 and 5, I have illustrated further modified form 01' myinvention which can be applied to practically all types of paiis andthis form includes a base disk 5 and an. annular flange 6 formedtherewith. The flange 6 has arranged in its interior surface a pluralityof superimposed aligned annular grooves 7 which as shown in Figure 3 areadapted to receive a plurality of like arranged ribs 8 which are formedabout the circumference of the body of the pail D adjacent its lowerend, and as the grooves and ribs are square in cross section and fiteach other, it will be obvious that it is practically impossible toremove the protector as shown in Figures 3, 4 and 5 after it has beenapplied to the pail, with the result casual removal is positivelyprevented. In Figure 4, I have illustrated the grooved form of myprotector secured to a pail indi cated by the letter E, having a truevertical wall, and when applied to such a pail, the annular grooves actin the capacity as suction means in that they set up a gripping actionto prevent the removal of. the protector as will be apparent.

From the above description and disclosure of the drawing, it will beobvious that I have provided a protector for dinner pails or the likewhich will protect the bottom thereof irom bethat the advantages andnovel features of myv invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

What I claim is:

In a protecting device for a pail, a plurality of superimposed alignedannular ribs formed with said pail upon the outer side and adjacent thebottom thereof, an elastic insulating means including a base diskengageable with the bottom of said pail, an annular flange formed withthe outer edge of the base disk and rising therefrom, said flange beingprovided with a plurality of annular grooves arranged to receive theribs, and said ribs and grooves being square in cross section and of asize to fit each other to prevent casual removal of the protector fromthe pail.
